Qian Xuesen, a famous scientist, said: "Nanotechnology is the focus of scientific and technological development in 2 1 century. This will be a technological revolution and an industrial revolution. "
The first industrial revolution:/kloc-The use of steam engines in the 8th century made Britain a world power. (millimeter technology)
The Second Industrial Revolution: Power technology made America a world power.
The Third Industrial Revolution: Microelectronics Technology Made Japan a World Power. (micro-technology)
Nanotechnology will trigger the fourth industrial revolution. It is internationally recognized as the most promising scientific and technological field in the 2/kloc-0 century and even the 22 nd century.
Now, whether you turn on the TV or the newspaper, you can see reports about nanotechnology everywhere.
What is nano?
Nano: Like meters and millimeters, it is a unit of length measurement in physics.
1 nanometer (nm) =11000 micron (um) =1/million millimeters (mm) =11million meters (m).
1 nm is equivalent to one fifth of the diameter of a hair.
If you put 1 nanometer on a table tennis ball, it is equivalent to the proportion of putting a table tennis ball on the earth, which is invisible to the naked eye. No one can find it before 1982.
It was not until 1982 that the scanning tunneling microscope was invented by American scientist Dr. laurel that humans saw nanoparticles. Since then, a new science, namely nanotechnology, has been born in the world. Dr laurel also won the 1986 nobel prize in physics.
What is nanotechnology?
Nanotechnology refers to the science that takes1–100 nanometer scale as the research object. More than 100 nm is called micron technology or far infrared technology.
Nano-materials: When a substance reaches the nano-structure after being treated by nanotechnology, it is called nano-materials.
Nano-materials have some peculiar physical and chemical properties that conventional materials do not have. When the substance reaches the nano-structure, its magnetism, conductivity, biological wave emission, ultraviolet blocking and catalytic decomposition will all undergo substantial changes.
Such as copper: good conductivity, but it is no longer conductive when it comes to nanostructures. Ceramics: very hard, but very brittle and easily broken. However, if the nano-structure is achieved, the hardness can reach 100 times that of steel, and the specific gravity is only 1/6 of steel, which can replace steel to build a thousand-storey building.
There are also various nano phenomena in nature. For example, hundreds of years after death, teeth and bones will not rot, because the bone density has reached nanostructure.
Lotus leaves do not touch water, because the fluff structure on the lotus leaves reaches 700 nanometers.
Countries all over the world have made many achievements in the research and application of nanotechnology:
Military: American F- 1 17, B-2 stealth fighter, Russian nuclear submarine. Because of the use of nano-paint, it can't be seen on the radar.
Medicine: 1 g nano medicine can replace 1 ton traditional medicine soup.
Nano-robots can enter blood vessels to clean thrombi, and can enter the body to kill cancer cells.
Nano-eyeballs can replace real eyeballs to see the wonderful world.
Nanoprobes can detect cancer cells early.
Nanotechnology conquers breast cancer.
China's nanotechnology is ahead of the world's advanced level in civil use.
The five-star red flag in Tiananmen Square is not afraid of rain and snow; The glass of the Capital Concert Hall need not be cleaned. It's all nanotechnology.
China is the first country in the world to produce nano-woven fabrics.
Enron's nanotechnology is at the international advanced level.
The raw material of nano-micron biochemical textiles produced by Enron Company is to collect and transport natural minerals beneficial to human body on the earth.
Using high-tech superfine grinding technology, it is processed into ultrafine particles of 20-30 nanometers, blended with polypropylene, and spun into nano-sized filaments and short fibers. Dr Zhang Lide, the chief nanotechnology scientist in China, called it "functional fiber". Woven into cloth, worn on the body, can play the role of disease prevention and health care, so: wear clothes and hats, sleep. It is a health care product worn on the body.
What effect does Enron's miniature biochemical textiles have on our human body? Because these minerals contain more than 20 kinds of trace elements and minerals, they have the following four functions after being treated by nanotechnology:
1. Emit and absorb biological waves.
Tested by China Institute of Metrology, the emissivity is above 9 1% and the length is 2–18 micron.
Second, release a large number of negative oxygen ions. Its negative oxygen ion concentration can reach 4800 ∕cm3.
Third, high-efficiency bacteriostasis and sterilization, blocking ultraviolet rays.
Tested by China Textile Academy, the bacteriostatic rates of Escherichia coli, Staphylococcus aureus and Candida albicans were 99.5%, 87.6% and 100% respectively. Therefore, nano underwear has a good conditioning effect on gynecological inflammation in women, prostatitis in men and frequent urination and urgency.
Fourth, strong catalytic decomposition. Its energy can reach 5–10 cm.
So what are these four effects related to our human health?
We explain the principle of disease prevention and fitness of enron nano products from the root of illness and death.
The number of deaths worldwide is about 5 1 10,000 every year. Except for car accidents and accidental deaths, the rest died of illness. In developed cities, it is difficult to find a dead old man and a really healthy person. Most people are in a sub-health state. Scientists have found that there are three main causes of illness and death: (1) biological wave disorder, (2) endocrine disorder and (3) microcirculation disorder.
First, biological wave disorder.
Biological wave is a characteristic wave existing in everyone, also called induction wave. Under normal circumstances, the human body can emit biological waves of 5.6–14 micron. Among them, the wavelength of 9.4 microns is the healthiest state of human body. Once the biological wave is disordered, it will cause nervous system diseases if it is lower than 9.4 microns or higher than 9.4 microns. For example: insomnia, dreaminess, migraine, neurasthenia, mental anxiety, backache, depression, nervous epilepsy, intermittent schizophrenia, etc. These diseases cost a lot of money to go to the hospital but can't be cured. However, if the human body is covered with nano-textiles, the biological wave of 2–18 micron emitted by nano-textiles can completely cover the biological wave of 5.6–14 micron of human body, and the biological wave of human body can be adjusted anytime and anywhere, so it has a good preventive and conditioning effect on nervous system diseases such as insomnia.
At the same time, the superposition of two kinds of biological waves produces friction vibration, which can activate human cells, which is equivalent to doing morning exercises.
Second, endocrine disorders.
Human body fluids and blood are weakly alkaline. Under normal circumstances, the PH value should be between 7.35 and 7.45. Due to the intake of high fat and high protein, most people will become acidic. More seriously, air pollution caused by factory exhaust and automobile exhaust, food pollution caused by pesticides, fertilizers and additives, and water pollution lead us to live in an acidic environment, which seriously damages the pH value of our human body. The most important cause of endocrine disorders is acid-base imbalance, which leads to a series of endocrine disorders, such as menopausal syndrome, diabetes, prostatitis, constipation and so on.
Enron nano textiles can produce a lot of negative oxygen ions. Negative oxygen ions are weakly alkaline, which can purify air, sterilize and neutralize acid toxins. They are called "vitamins in the air" in medicine, and the content of negative oxygen ions is relatively high at seaside, forest and waterfall, with an average of about 5000 ∕cm3. The negative oxygen ions produced by nano-cloth can reach 4880 ∕cm3, which is very close to the content of forests and waterfalls. Therefore, the nano-cloth can be absorbed by the skin, neutralize acidic substances and metabolic toxins, adjust the acid-base balance of the human body, and thus achieve the effect of regulating endocrine disorders.
Third, microcirculation disorder.
Zhao Kesen, vice president of China Microcirculation Society, pointed out that microcirculatory disturbance can cause 465,438+04 diseases and 33 malignant tumors.
The flow of blood, lymph and tissue fluid between arterioles, capillaries and venules in human body is called microcirculation. Microcirculation has four characteristics:
1. Duo: There are more than 30 billion blood vessels in the whole body.
2. Length: The total length is about 9–110000 km. It can go around the earth for two and a half weeks.
3. Fine: the thinnest capillary is 1∕20 of the hair diameter.
4. Thin: The thinnest blood vessel wall is only 1∕ 100 of ordinary white paper.
Due to these four characteristics of microcirculation, coupled with the increasing improvement of people's living standards, blood lipids are viscous or hyperlipidemia, and the blood flow speed is slow, which is easy to cause capillary deformation or blockage, which will cause ischemic and hypoxic cell necrosis of organs and tissues, thus causing human pain, cold, numbness and other symptoms, as well as common diseases such as hypertension, coronary heart disease and cerebral thrombosis. In severe cases, it can lead to stroke, cerebral hemorrhage and hemiplegia. Therefore, medically speaking, the microcirculation is unobstructed and all diseases are not born.
Microcirculatory disturbance is the source of all diseases.
Nano-cloth has strong catalytic decomposition. As long as the cloth is close to the skin, its catalytic decomposition energy can penetrate the depth of 5- 10 cm, decompose the garbage on the blood vessel wall and excrete it through metabolism, thus achieving the effect of adjuvant treatment of hypertension and cardiovascular and cerebrovascular diseases.
